I would just add, again, joint support ship is the name of the project. They are much broader but, as the deputy said, principally they are warships. They are designed, have survivability, different things to do and they are ships we're bringing into service for at least 30 years. If you look at the two that have been replaced, they were in service almost 45 years after different upgrades.
The interim contract is five years plus options. It's very different. It is more in the short term. It is, I think, a very impressive capability we're seeing coming online early next year that will serve the navy, from what we see, well as it comes together, but it really is bringing those support ships into the task group.
The way our navy operates as a task group, that support ship carries a significant amount of the aircraft and other things into harm's way with the task group.
